Chemical AAQ helps blind mice to see

The video discusses degeneration in the retina, which can lead to blindness by affecting rods and cones. However, the underlying nerve network often remains intact. A compound called AAQ has been developed to help restore vision by acting as a photo switch that binds to protein ion channels in the retina. When exposed to light, AAQ activates, allowing ions to flow and neurons to react similarly to rods and cones. An experiment with mice demonstrated that those injected with AAQ responded to light like normal-sighted mice, while untreated mice did not.

What was the experimental setup used to test the effects of AAQ on mice?

Compare the behavior of normal seeing mice with those that received the AAQ injection.
